1mm x 1mm Video Filter Amplifier with
Automatic Shutdown and 2V/V Gain
Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the
MAX9515 is an ultra-small standard-definition video filter amplifier with automatic shutdown.
The automatic shutdown circuitry eliminates the need
for a shutdown control. This feature provides intelligent
power management by disabling the filter and output
amplifier in the absence of a video input signal and/or
an output video load. At shutdown, the device only consumes 5µA.
The MAX9515 features an internal reconstruction filter
that smoothes the steps and reduces the spikes on the
video signal from the video digital-to-analog converter
(DAC). The reconstruction filter typically has ±1dB
passband flatness to 9MHz and typically 50dB of attenuation at 27MHz.
The video input to the MAX9515 can be directly connected to the DAC output. The MAX9515 has an internal fixed gain of 2V/V and expects a nominal full-scale
video input signal of 1VP-P. The MAX9515 is specified
to operate over the -40°C to +125°C automotive temperature range.

Detailed Description
The MAX9515 is an ultra-small, standard-definition
video filter amplifier with automatic shutdown. Automatic
shutdown circuitry provides intelligent power management by disabling the filter and output amplifier in the
absence of an input video signal and/or output load.
An internal reconstruction filter smoothes the steps and
reduces the spikes on the video signal from the video
digital-to-analog converter. The reconstruction filter typically has ±1dB passband flatness to 9MHz and typically 50dB of attenuation at 27MHz. The MAX9515 has
an internal fixed gain of 2V/V and expects a nominal
full-scale video input signal of 1VP-P.

connecting an internal 15kΩ pullup resistor to the output for 1ms. If the output is pulled up, no load is present. If the output stays low, a load is connected.
If the input video signal is present and a load is connected to the output, the filter and amplifier turn on and
remain on until the output load is disconnected.
Automatic shutdown intelligently reduces the supply
current based on the input signal presence and output
loading (Figure 3).
When the amplifier is on, it continually checks if the
load has been disconnected by detecting if the amplifier output is sourcing current during a horizontal line
time. If no sourcing current is detected within one horizontal line time (approximately 64µs), the load has
been disconnected and the amplifier returns to activedetect mode. If, at any time, the input video signal is
removed, the MAX9515 returns to standby mode.

Automatic Shutdown
The MAX9515 automatic shutdown circuitry reduces
power consumption when there is no active video input
signal or an output load. In shutdown, the supply current is reduced to 5µA. The video amplifier only turns
on when both an active video input signal and an output load are present.
The MAX9515 slices the IN signal at 4.7% of the power
supply (155mV for a 3.3V supply). If the transitions
occur at a rate of 7.3kHz or higher, a video signal is
present. When the MAX9515 detects a video signal
with sync at the input, the control logic enters the
active-detect mode and enables the load sense circuitry (Figure 2). The supply current increases from 5µA to
9µA typically.
If an output load is not connected to the amplifier, the
MAX9515 remains in active-detect mode. Eight times
per second, the load-sense circuit checks for a load by

Input
Output
The MAX9515 video input should be directly connected
to the output of the video current DAC. DC-coupling
ensures that the input signal is ground referenced such
that the sync tip of the composite video signal is within
50mV of ground. Any standard-definition video signal
can be applied to the input as long as the signal is
between ground and 1.05V when VDD = 2.7V.
The MAX9515 output expects to drive a DC-coupled
load to ground. The amplifier output stage needs about
300mV of headroom from either supply rail. The device
has an internal level shift circuit that positions the sync
tip at approximately 300mV at the output.
Video Reconstruction Filter
The filter passband (±1dB) is typically 9MHz, which
makes the device suitable for standard-definition video
signals from all sources (e.g., broadcast and DVD).
Broadcast video signals are channel limited: NTSC signals have 4.2MHz bandwidth, and PAL signals have
5MHz of bandwidth. Video signals from a DVD player,
however, are not channel limited; so the bandwidth of
DVD video signals approaches the Nyquist limit of
6.75MHz. (Recommendation ITU-R BT.601-5 specifies
13.5MHz as the sampling rate for standard-definition
video). Therefore, the maximum bandwidth of the signal
is 6.75MHz. To ease the filtering requirements, most
modern video systems over sample by two times,
clocking the video current DAC at 27MHz.
Applications Information
Power-Supply Bypassing and Ground
The MAX9515 operates from a single-supply voltage
down to 2.7V, allowing for low-power operation. Bypass
VDD to GND with a 0.1µF capacitor. Place all external
components as close as possible to the device.
